Looking for a practical guide to using mixed methodologies? Authors Abbas Tashakkori and Charles Teddlie explore the most resourceful way to combine qualitative and quantitative methodologies. Beginning with a discussion of the paradigm wars between positivism and constructivism, Mixed Methodology explains the differences between using mixed methods in only the research methodology portion of a study versus using mixed model studies across all phases of the research process, and then presents a typology of mixed methods and mixed model studies. The authors next examine sampling issues, reliability and validity questions, data collection procedures (including self-report techniques, questionnaires, observational methods, interaction analysis, and archival data/cultural artifacts), and data analysis techniques. Tashakkori and Teddlie conclude with detailed examples of current published and unpublished research that utilize mixed approaches. Researchers wanting to learn how to think about and utilize mixed methods in their studies will find this an indispensable guide for their work.
